EPR RECLOSER
1) Pin R is connected to Ground.
2) RVD Resistance : 10MΩ
3) For RVD Protection, MOV is connected between
Phase and Ground.
y For voltage measuring, use High Impedance AC
Voltmeter(Digital Multimeter) at Output Pin.
y Voltage Measuring Method 1
measure MOV voltage.
(measure a voltage between MOV arms)
y Voltage Measuring Method 2
Place the capacitor(C2) in parallel with MOV. and
measure MOV voltage.
